Abstract 

A new CMOS active pixel ranging sensor is presented, realized as a 1x64 array of 30$\mu$m x 30$\mu$m lock-in pixels. The sensor is based on the current-assisted photonic demodulator, implemented in Standard CMOS 0.35 $\mu$m technology. The ranging pixel achieves 75\% Fill-Factor, 0.22 A/W total Q.E. and a demodulation bandwidth up to 70 MHz, both at 860nm light. Range-finding is achieved through Modulated Wave Time-of-Flight measurements with a modulation frequency of 20MHz. Distance measurements are presented. This sensor represents the first step towards integrating CAPD-based lock-in pixels in large TOF CMOS ranging systems.
